Embodiment Construction

[0058] see now figure 1 with figure 2 , a nicotine powder delivery system comprising an inhaler article 1 comprising an inhaler body 2 extending between a mouthpiece portion 5 and a distal portion 3 or end cap element 3 . A nicotine powder container 9 delimiting a capsule chamber 8 is placed inside the inhaler body 2 and between the mouthpiece part 5 and the distal part 3 . The air inlet 4 extends through the inhaler body 2 and into the nicotine powder container 9 . A mouthpiece air channel 10 fluidly connects the nicotine powder container 9 with the proximal end of the mouthpiece 5 . The nicotine powder capsule 6 is placed in the nicotine powder container 9 . The nicotine-containing particles 7 and optionally the flavor-containing particles are housed within the nicotine powder capsule 6 . As mentioned above, the piercing element may pass through the distal part 3 or end cap element 3 and form a single hole into the nicotine powder capsule 6 for consumption. Airflow ma...

Abstract

A nicotine powder delivery system includes an inhaler article and a nicotine powder capsule disposed within the inhaler article. The nicotine powder capsule rotates about a longitudinal axis when airflows through the inhaler article.

Description

technical field [0001] The present disclosure relates to a nicotine powder delivery system comprising an inhaler article and a nicotine powder capsule disposed within the inhaler article. The nicotine powder capsule is rotatable about a longitudinal axis as air flows through the inhaler article. Background technique [0002] Dry powder inhalers (DPIs) are known and used for the treatment of respiratory diseases by delivering a dry powder containing a drug in aerosol form to the respiratory tract of a patient via inhalation. For delivery into the lungs, particles in the 1 to 5 micron range are preferred. In pharmaceutical dry powders, the active pharmaceutical ingredient (API) aggregates on the surface of larger carrier particles such as lactose. DPIs operate complex mechanisms to ensure that such agglomerates disperse, disintegrate or disaggregate before the API can be inhaled into the lungs. Drug dry powders containing lactose as a carrier can be in the range of 20 to 10...
